A graph that lies entirely in the x-axis is one that has a y-intercept located in upper part of the y-axis. Also, the vertices are located at the upper part or the values are positive and is opening upward. From the choice given, the best answer is option 3 where the vertex is at the coordinates (7,7) and the parabola is facing up.
